NEW YORK, Oct. 22 (UPI) -- The researchers who endorsed Dr. Mehment Oz's green coffee bean extract have retracted their study endorsing the pills, saying it was based on fake research.
The paper "Randomized, double-blind, placebo-controlled, linear dose, crossover study to evaluate the efficacy and safety of a green coffee bean extract in overweight subjects" was published in 2012 endorsing the pills.
